Use and scope of application

NMDZ 15L series plastic case type earth leakage circuit breaker (referred to as leakage circuit breaker) is suitable for AC 50Hz, rated voltage up to 380 (400) v, rated current to 100A, for personal contact and leakage protection. It can also be used to protect the line from overload and short circuit as infrequent switching of the line and infrequent starting of the motor.

The basic mechanism derived from the NMDZ15 series circuit breaker is the same as the NMDZ15. In the lower part, the zero-sequence transformer, the leakage release and the test device are added to form a leakage protection device.
